Sheet material



The single FIGURE is a fragmentary plan view of sheet material showing our new design, the sheet material repeating this pattern endlessly in each direction. The broken lines around the design define one unit of the claimed design, which can repeat in one or more directions. The broken lines form no part of the claimed design.

The appearance of the side opposite that shown in the FIGURE is not claimed.

The material is of insignificant thickness and so the edge views are linear and their appearance is not claimed. 

The ornamental design for sheet material, as shown and described.
